Ithaca Preps to Drill Hurricane Appraisal Well
Apr 19, 2012 – Ithaca Energy reported it will commence drilling the Hurricane appraisal well later this year. The spud date is later than originally anticipated due to delays in the drilling program being performed for other operators, prior to the contracted rig being moved to the Hurricane well location. It is estimated Hurricane holds gross 3P reserves volume of 13 MMboe.
Project Details: Hurricane
Providence IDs Two Prospects in LO 11/12
Apr 19, 2012 – Providence Resources believes it has identified two gas prospects approximately 45 miles off the west coast of Ireland, and close to Shell‘s Corrib gas field. Providence said that an initial technical evaluation of Licensing Option 11/12 has revealed the presence of two prospects in the Slyne Basin that it has called “Kylemore” and “Shannon” – both similar in age to the Corrib field. The Kylemore prospect is interpreted as a mid-basinal inverted four-way dip-closed anticline based on a combination of 2D and 3D seismic data. The most recent mapping of the Kylemore prospect indicated that it is structurally directly analogous to the Corrib gas field, with volumetric analysis based on available maps indicating potential gas in place of up to 228 billion standard cubic feet. The Shannon structure, which was drilled by Enterprise Oil in 1999, demonstrates significant structural closure covering around 9 square miles, the LO 11/12 partners believe that Shannon warrants a complete reevaluation in the context of any remaining resource potential. The company plans to apply modern seismic processing technologies to the available 3D seismic data in order to better quantify any remaining resource potential in the area.
Project Details: Shannon
Total Spuds Relief Well, Preps Well Kill at Elgin
Apr 18, 2012 – Total has sent a team of engineers to its Elgin platform to conduct further preparations for work needed to end an ongoing natural gas leak. In addition to the well-kill operation, the operator has begun drilling one of two planned relief wells.

Dana Spuds Platypus Appraisal Well
Apr 17, 2012 – Dana has spud an appraisal well on the Platypus gas field in the UK sector of the North Sea. The Rotliegendes gas accumulation at Platypus was discovered in 2010 by the Dana Petroleum plc operated 48/1a-5 well, which encountered 218 vertical feet (66 meters) of gas bearing sands and has the potential to contain up to 180 billion cubic feet of gas in place. Drilling operations are being performed by the ENSCO 80 (250′ ILC) drilling rig. This well will be drilled horizontally through the Rotliegendes gas reservoir to confirm deliverability and is expected to be suspended for reuse as a gas producer.
Project Details: Platypus
Wintershall Hits Oil Pay in Skarfjell
Apr 16, 2012 – Wintershall has made an oil discovery at its Skarfjell prospect in the Norwegian sector of the North Sea. The wildcat well 35/9-7 found Upper Jurassic reservoir sands of “good quality” containing light oil with “a significant oil column” said the firm. So far, Wintershall added, the resource is estimated to range between 60 million and 160 million barrels of recoverable oil, although commercial viability, as well as potential further upside, will need to be confirmed through appraisal drilling. The primary exploration target of well 35/9-7 was to prove hydrocarbons in the Upper Jurassic reservoir rocks. The well was drilled by the Songa Delta (mid-water semisub) in a water depth of 1,237 feet (377 meters) in PL 418.
Project Details: Skarfjell
Norway Greenlights Lundin’s $4.2B Edvard Grieg Oil Field
Apr 13, 2012 – The Norwegian government has approved the $4.2 billion development of the Edvard Grieg (formerly Luno) oil field, the first field offshore Norway operated by Lundin Petroleum. The Edvard Grieg area contains 186 million barrels of oil equivalent, and peak production is expected to be 90,000 boepd. Production at Edvard Grieg will be combined with the production of the nearby Draupne, and studies are being made to find the best ways of exporting oil and gas from the Utsira Height area.
Project Details: Edvard Grieg (Luno, Draupne) Project
Framo Engineering to Design, Construct Gullfaks Subsea Gas Compression Plant
Apr 13, 2012 – Statoil has awarded Framo Engineering a contract for the design and construction of the Gullfaks subsea gas compression plant. The operator said that Gullfaks may become one of the first installations worldwide to employ subsea gas compression. The mature Gullfaks field is experiencing a decline in natural reservoir pressure, so the field may need boosting in the form of compression in order to produce more gas and bring the gas up to the platform. In 2011, Statoil and partner Petoro decided to choose a subsea solution as the preferred concept for gas compression some nine miles (15 kilometers) from the Gullfaks C platform. This may increase the production from the field by 3 billion cubic meters of gas, enabling Gullfaks to sustain plateau production for gas export. The current recovery rate on the field is 62 percent. A combination of subsea compression and conventional low-pressure production in a later phase may increase this to 74 percent. This is the first delivery by Framo Engineering to Statoil within engineering, procurement and construction (EPC) of subsea compression facilities. Contracts for platform modifications and marine operations in connection with the Gullfaks development will be awarded during the summer/autumn of 2012, subject to a positive investment decision.

Lansdowne Updates Seismic Ops Offshore Ireland
Apr 13, 2012 – Lansdowne Oil & Gas has processed a 3D seismic survey over the Rosscarbery license area, including the Galley Head gas discovery and other prospects in the North Celtic Sea, offshore Ireland. Following interpretation of the 3D seismic, the Galley Head gas discovery is now interpreted by Lansdowne as having gross P50 in-place volume of 30 BSCF GIIP with 25 BSCF potentially technically recoverable. The Carrigaline gas discovery lies outside the area covered by the 2011 3D seismic survey and remains unchanged from the February 2011 CPR which calculated gross P50 in-place volume of 81.8 BSCF with P50 technically recoverable gas of 60.8 BSCF.
Project Details: Rosscarbery

BHP Billiton Requests SC55 Exploration Extension
Apr 16, 2012 – BHP Billiton has requested that the Department of Energy extend the current exploration sub-phase 4 of SC55 by 18 months. If approved by the DOE, this would extend the current contractual deadline to complete drilling of the commitment well from August 5, 2012 to February 5, 2014. The operator has requested this extension in order to secure an appropriate ultra deepwater rig with specialized well control equipment for drilling operations on the proposed Cinco prospect. No date has been set for drilling operations until a rig can be secured.
Project Details: Cinco
Premier to P&A Biawak Besar
Apr 13, 2012 – Premier Oil will plug and abandon its Biawak Besar-1x exploration well offshore Indonesia after it reached its targeted depth of 5,950 feet (1,814 meters) by the West Callisto jackup (400′ ILC). Although logs for the Biawak Besar-1x well showed better-than-expected sand quality, the sands were water wet. The results from the well will be incorporated into the firm’s existing 3D seismic database to determine the cause of the amplitude response and its implications for the future prospectivity of the targeted play.

Anadarko Further Appraises Heidelberg
Apr 19, 2012 – Anadarko has further appraised the Heidelberg discovery in the deepwater Gulf of Mexico after drilling two appraisal wells (GC 903-3 and GC 903-3ST1). The two wells were drilled in order to appraise the extension of the Heidelberg discovery made in 2009. The Heidelberg appraisal well GC 903-3 was drilled in a water depth of 5,260 feet (1,603 meters) and reached a total depth of 31,030 feet (9,460 meters) of measured depth. The well was sidetracked down dip (GC 903-3ST1 well) to a total depth of 30,440 feet (9,278 meters) of measured depth, indicating an oil water contact at approximately 700 feet (213 meters) deeper than the previous oil discovery well and significantly increasing the field’s aerial extent. Estimated recoverable resources could reach 200 million barrels of oil. Data is being evaluated in order to accelerate the overall sanctioning process for this project.
